I have a 2000 Escalade, every so often it will start, run for about 1/2 a second then die. When I go to restart, it just turns over. In the past, i'd let it sit for several hours then it starts right up. Runs fine for months, then does it again. I read on here almost a year ago about someone having a similar problem and it turned out to be the Security system. They posted a method to reset it, (something like, turn the key to the on position for 15-17 minutes remove key open and close door then it should start). Is this the correct procedure, or am I missing a step? I've spoken with several other GM Truck owners that have experienced the same problem. Most of them had to have the Alarm System replaced. Please give me more insite to what this may be, and how to correct it. Thanks in advance

i had a complete tune up less than a year ago (wires cap rotor distrib replaced.) new fuel pump year and half ago.
the security light id no illuminated once i try to start it. I'm not sure what the fuel pressure is, I do not have the tool to test that.

You really need to find out what you are missing when truck wont start: spark or fuel. There maybe codes stored although SES light is not on. Theft deterrent faults will not always turn on SES. Fuel pressure gauge and spark tester can be found at most auto parts stores. An FSM would be great to have. Things to look at: coil wire routed too close to engine bracket and crank sensor connector for oil leak or corrosion.

I had it towed to my Mechanic, it turned out to be the Iginiton Module. Thanks again for your help.
